Silicon Calcium Alloy
Products Description
Silicon-calcium alloy, composed of silicon (Si) and calcium (Ca), combines silicon's strong deoxidizing capability with calcium's shape-modifying and desulfurizing effects. When added to molten steel, it rapidly and uniformly reacts with impurities, helping to enhance the mechanical properties and surface quality of steel. It is highly suitable for the production and purification processes of conventional carbon steels, alloy steels, and certain specialty steels.
Product Advantages
Dual Function
Combines deoxidation and desulfurization capabilities, delivering multiple improvements with a single addition.

Usage Recommendations
- Addition Point: Depending on process requirements, add at the converter, ladle, or ladle bottom as appropriate;
- Dosage: We recommend initial testing based on process formulations, followed by fine-tuning based on laboratory results;
- Operational Precautions: Avoid moisture exposure; minimize dust generation during addition; wear protective gear when necessary;
- Record Management: Document batch numbers, dosage amounts, and factory test results to facilitate process traceability
FAQ
Q: Can calcium silicate alloy completely replace silicon or calcium alone?
A: In many operating conditions, calcium silicate alloy can substitute for single additives, but the optimal ratio depends on specific processes and target compositions. We recommend small-batch trials and relying on laboratory test results.
Q: How to select the appropriate particle size?
A: Fine particles dissolve rapidly and react quickly but generate dust easily; coarse particles react more slowly and are easier to control. Generally, choose the appropriate particle size based on process rhythm and addition method.
Q: What are the delivery times and minimum order quantities?
A: Standard specifications support small-batch shipments, while bulk orders benefit from more favorable delivery times. Please contact sales for specific delivery schedules and MOQs.
